asterisk users - Jul 2005 - How to adjust codec voice detection? Changin RxGain does not help me...

Hi,

Problem: When talking to someone (from pstn) and this person is not
talking loud, the voice is cut by Asterisk. I tried increase RxGain but
it changed nothing (was talking louder but voice still cut.) I use XLite
as soft phone.

I think this is probably a codec setting... but how do I check that on
server side?

I just don't know what to do. All works fine (asteriskathome) but I
always have problems about the sound being not enought loud and being
cut (as if it was voice detection... but not working properly.)

Thanks for any help.

Stop using Xlite :) 

 Seriously, I had it setup on WinXP with an onboard sound card and it
sounded like you are describing. Even after setting the gains using a
local 0db Miliwatt test it didn't sound very good.

I added a polycom 501 to the system and it sounds a million times
better, I bet even a grandstream budget phone will sound better.

This is not Asterisk.  Asterisk does not do Voice Activity Detection. 
X-Lite however does.  Have a look through its settings.
